If the stacksize of the players is zero too, then the following is the case.
SpadeEye waits 500ms till the pokerclient software delivers the playerlist.
If this not happens, then SpadeEye moves on to the next table, and displays 0.

The reason why the pokerclient software don't show the playerlist could be, that your or their internetconnection is overloaded.

You can try to raise the value SpadeEye waits for the playerlist, by going to the options->general-tab.
Raise the value "how long to wait for playerlist". By raising this value the scanningtime will be increased...
